Amniotic fluid, chorionic villi, extracted fetal DNA, or pregnancy-loss material; a maternal sample may be required for contamination testing.
DIAGNOSTIC METHODS
Prenatal Array CGH
Investigates chromosomal deletions or duplications in a prenatal sample when imaging or another finding suggests imbalance.
Prenatal genome-wide array CGH with indicative resolution around 50–100 kb.
Prenatal interpretation of copy-number findings and follow-up recommendations.
Typically about 2 weeks after accepted sample receipt.
CLINICAL VALUE
Where this test is strongest
✓About 2-week prenatal workflow
✓Genome-wide CNV analysis
✓Maternal-cell contamination planning
✓Clinically interpreted report
LIMITATIONS
What must remain visible
!Does not replace exome testing for sequence-level disorders.
!The case and sample must be reviewed before shipment.
GENE & ANALYTICAL SCOPE
Scope confirmed per case
No gene list: this is a genome-wide fetal copy-number method.
Prenatal genome-wide CNV scopeCase-specific analytical scope+
Deletions and duplications at the confirmed platform resolution.
No fixed gene-by-gene list applies to this scope.
